What is produced by recycling used household oil?

Treated oil can be used as fuel for diesel engines by transforming the ester into biodiesel.

Oils and fats can also be used for lubrication. Using a process similar to biodiesel production, new biolubricants have been obtained, which are biodegradable and less polluting than mineral oils.

An important application to be developed in the coming years is the production of bioplastics from microorganisms fed with waste oils.
